I made an app, MyCycle (it has nothing to do with the female biological cycle, had I known that google will relate it to this I would have named it differently), which isn't very popular. But I didn't get any useful reviews. Here is a suggestion to Android Market, "Why not allow apps to submit feedback through some API??? Is it that difficult to make a Android Market API?". I don't see a reason why Google has not done it yet. Well, for the time being I just created a website of my own, http://www.droidfeedback.com
In case you also feel the same, here are some simple steps you need to get started:
1. Login to www.droidfeedback.com
2. Register your app
3. Add some questions, you want to ask your users
4. For your app, download the jar on the website, or grab the code from googlecode link given.
Setting up the feedback form is simple, and I feel it is an easy step towards getting some useful feedback. If you don't like the website, I sincerely apologize. This is my first web programming experience and I am no designer. I would be moving all the website code on github soon, so anyone interested in making it look good is welcome.
Have fun!
